In case you missed the vice presidential debate -- and who didn't? -- the most memorable moment in my view came when Indiana Gov. Mike Pence sounded shocked, shocked, at the very idea that a black police officer could be biased against black people.

As with many topics, Donald Trump doesn't know much about the policing policy widely known as "stop and frisk," but that doesn't deter him one bit from Trump-splaining it to us with unbridled self-confidence.
